Can someone look over my answers please?

Similar triangles \(\dfrac{8}{8+32} = \dfrac{x}{x+36}\)

geerky42 (geerky42):

First one isn't right.

Directrix (directrix):

@SFAdrienne If a line is parallel to one side of a triangle and intersects the other two, then it divides them proportionately. So, for the first problem, use the proportion 8/32 = x/36 to solve for x.

Thank you. :)

Directrix (directrix):

@SFAdrienne I think the second problem is incorrect. If 3 parallel lines intersect two transversals, then they divide them proportionately. So, 24/x = 36/12. Solve for x and see what you think.
